合理地确定年伐量的大小,首先依赖于备有的成熟林,应该具有这样的计算和规定,仅仅是成熟林才进行采伐,在上述条件下,森林利用应该是永续的,也就是说,年年采伐,同时比较均匀,为了规定利用量,要满足这些条件,就需要有林令分布资料,和同时考虑成熟林木的积累程度,显而易见,成熟林的积累动态可用专门的图1表示。 Reasonable determination of the size of annual cut, first of all depends on the available mature forest, there should be such a calculation and regulation, only mature forest for logging, under the above conditions, the use of forests should be sustainable, that is , Annual harvesting, and at the same time more uniform, in order to regulate the utilization, to meet these conditions, you need to have an order distribution information, and also consider the level of mature forest accumulation, it is clear that the accumulation of mature forest available special Figure 1 said.
